WILLIAM TE GUSSINKLO, OF NEW YORK, N. Y.

Ho Drawing. Application filed Ju1y 12,

To all whom it may concern:

Be it known that I, WILLIAM Tn Gus- SINKLO, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and 1m proved Glycerine Soap and Process of Mak-' ing Same, of which the following is a full, clear, and exact description.

This invention relates to soaps, and has for an object to provide an improved soap wherein the same contains a large percentage of glycerine.

Another object is to provide a soap wherein glycerine may be used up to 90% of the entire volume.

In carrying out the invention and producing a soap embodying the invention, a suitable soap as now manufactured may be used and may be mixed with the glycerine, as hereinafter fully described, or a special soap may be provided and mixed or co1npounded with glycerine, as hereinafter described. A suitable soap for compounding with glycerine may be made from cocoanut oil and caustic soda lye. Aconvenient proportion of these ingredients may be 300 pounds of cocoanut oil added to 150 pounds of 38 B. caustic soda lye. These two ingredients may be saponified or made into soap by first heating the oil to about 100 F., then adding gradually the lye while continually stirring the mixture until the lye is thoroughly compounded with the oil, the temperature being maintained substantially about 100 F., though it might be maintained at a somewhat higher temperature if desired. After the ingredients have been thoroughly combined, the mixture or compound is set aside in frames or receptacles of any kind until cold, whereupon the mixture will solidify. Ordinarily, this takes about one day. After the soap has solidified, it is then ready to be mixed with the glycerine. In preparing this soap for mixing with glycerine, the same is chipped or Jinely divided and gradually fed to boiling glycerine, which glycerine is maintained at the boiling point until the soap fed thereto has dissolved. A desirable glycerine soap will be produced by using five hundred pounds of glycerine combined with the above ingre clients as specified. The amount of glycer- GLYCERINE SOAP AND PROCESS OF MAKING SAME.

ine and soap may be varied according to the produce desired, as, for instance, from 1% to 90% of glycerine. It will be, of course, evident that 1% of glycerine would have but little effect in changing the action of the soap, whereas 90% would make the soap somewhat soft, though it has been found that a proportionn of 7 5% glycerine and 25% soap as above outlined will produce a very desirable hard soap. After the glycerine and first mentioned soap have been mixed, the finished soap embodying the invention will result, and after this finished soap has been allowed to cool, it will harden and then it will be ready to cut or press into any desired shape. In providing a large content of glycerine as above outlined, the glycerine will completely neutralize the lye set free by the water in washing when using the soap, thus making it harmless to tender skins. In providing a given content for a given batch of soap, the same may include cocoanut oil, caustic soda lye and glycerine.

I claim: I

1. A hard glycerine soap formed of a commercial soda soap and a glycerine content of from 75% to 90%.

2. A hard glycerine soap formed from a vegetable oil, caustic soda lye and glycerine, the glycerine content being more than 50% to 90% of the volume.

3. A hard soap formed from cocoanut oil, caustic soda lye and glycerine, the glycerine being not less than 7 5% of the volume.

4. A hard glycerine soap formed from the following ingredients in the following proportion: 300 pounds cocoanut oil, 150 pounds caustic soda lye and glycerine, the glycerine being more than 50% of the vol nine.

5. A process of making a soap having a content of glycerine which is greater than 50% which comprises finely dividing a soap having a content of lye and vegetable oil, heating a quantity of glycerine until the same reaches the boiling point, feeding the finely divided soap while cold into the hot glycerine and maintaining the glycerine at the boiling point until all the soap has been dissolved and then cooling the same.
